Answer:
X = 11
Step-by-step explanation:
So, in order to solve this equation, we need to isolate x.
So, we are going to subtract 8x from the right side to get the x on one side. The equation should look like this:
-2x + 7 = -15
Now in order to get x all alone on one side, we need to subtract 7 from the left side.
-2x = -22
Now we just have to divide the -2 from x.
X = 11
The volume of a figure is the number of cubic units present in the figure. For this problem, we assume that the figure would be a rectangular box in shape. So, the volume would be calculated by the product of its length, width and height or in this case the depth. We calculate the volume of water as follows:
Volume = 4.50 ft x 7.00 ft x 5.00 in ( 1 ft / 12 in )
Volume = 13.125 ft^3
We need to convert the resulting volume in liters. We do as follows:
Volume = 13.125 ft^3 ( 0.3048 m / 1 ft )^3 ( 1000 L / 1 m^3 )
Volume = 371.66 L
We need to compute for the length of each trophy given that one trophy is 5 inches wider than the other.
Let x be the length of the first trophy.
Let x+5 be the length of the second trophy
The solution is shown below:
x + (x + 5) = 17
x + x + 5 =17
2x =17 -5
2x = 12
x = 12/2
x=6 (for the first trophy)
x + 5 = 6+5 = 11 (for the second trophy)
The first trophy is 6 inches wide while the second trophy is 11 inches wide.
Answer:
1 inche
Step-by-step explanation:
We're told that distance traveled in t hours is 400t. So the distance traveled in 3 hours is 400(3), or 1200 miles.
